For coastal Florida homes, Sherwin-Williams Duration and SuperPaint exterior lines provide the best balance of salt-air resistance, UV stability, and mildew protection. Grove Street Painting includes rust-inhibitive primers on metal and trim sealing on every exterior project.
Coastal Florida exteriors face three accelerated degradation factors: salt air corrosion, intense UV radiation (Florida receives 20-30% more UV than northern states), and high humidity that promotes mildew growth. Premium 100% acrylic latex coatings resist all three better than bargain alternatives.
Our exterior process includes rust-inhibitive primer on all exposed metal (downspouts, railings, door hardware, mailbox posts), elastomeric caulking at trim-to-stucco joints, and UV-resistant topcoats with built-in mildewcide. For barrier-island properties on Siesta Key, Longboat Key, and Casey Key, we add an additional primer coat on salt-facing elevations.
Product selection varies by substrate. Stucco gets elastomeric coatings that bridge hairline cracks. Wood trim gets alkyd-modified primers for maximum adhesion. Concrete block gets masonry-specific primers. See our full exterior painting process with product specifications for each surface type.
